A spark plug for an internal combustion engine is proposed, having at least two electrodes (9, 11), one of which at least two electrodes is at least one middle electrode (11) and another electrode of the at least two electrodes is at least one ground electrode (9), and between the at least one ground electrode (9) and the at least one middle electrode (11), a spark gap (13) is formed. Each of the at least two electrodes (9, 11) has an electrode base body (93, 113). At least one electrode has a region (95, 115) that is highly resistant to electrode erosion and that forms at least a part of the end face, oriented toward the spark gap, of the electrode (97, 117). The highly electrode-erosion-resistant-region (95, 115) comprises an alloy which has at least the elements iridium and nickel.
